Studies on heterogeneous lipopolysaccharide fractions of Vibrio cholerae 569B

Abstract:
By SDS-PAGE or gel filtration on Sephadex G-25, lipopolysaccharide (LPS) isolated from Vibrio cholerae 569B (Inaba) can be separated into two distinct fractions, one corresponding to smooth LPS and the other to rough LPS. Pulse-labelling of LPS with [14C]glucose showed that the rough form is synthesized first followed by the biosynthesis of the smooth form. A preferential release of the smooth LPS of V. cholerae 569B was also detected during normal growth of cells.

Formation of Lipopolysaccharides
Lipopolysaccharides (LPS) are crucial components of the outer membrane of Gram-negative bacteria, serving both structural and functional roles. It contributes to membrane stability and protects bacteria from host immune responses. LPS is composed of three major regions—lipid A, a core oligosaccharide, and an O antigen. The biosynthesis and assembly of LPS involve a highly coordinated set of enzymatic reactions and transport mechanisms. Additionally, LPS is recognized as an endotoxin, triggering...
Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
